Hothouses (or Hot House Blooms, French: Serres chaudes) (1889) is a book of symbolist poetry by the Belgian Nobel laureate Maurice Maeterlinck.

Serres chaudes has been translated into English by Richard Howard.

This edition, published by Princeton University Press also contains a short prose work, The Massacre of the Innocents, inspired by a Brueghel painting of the same name, as well as illustrations by George Minne that appeared in the original volume.

"Serre chaude," "Serre d'ennui," "Lassitude," "Fauves las," and "Oraison" were all set to music by French composer Ernest Chausson.

"Feuillage du cœur" was set to music by Arnold Schoenberg under the name Herzgewächse and by the Belgian composer Serge Verstockt (original title).
